Steel Shot: The Unsung Hero in the Automotive Industry
In the field of precision manufacturing, high-performance Abrasive Steel shot plays an indispensable unsung hero role. Its uniform spherical shape, controllable hardness, high toughness, and excellent recyclability perfectly meet the green production requirements of the automotive industry.
Through Shot Peening, steel shot can efficiently remove oxide scale, rust, and burrs from parts such as engine blocks and crankshafts, ensuring the cleanliness of subsequent painting or electroplating, and is more environmentally friendly than chemical pickling.
High-speed steel shot bombarding parts such as springs and gears can generate residual compressive stress, inhibiting crack formation and extending the fatigue life of springs by 30%-50%, and increasing the contact fatigue strength of gears by 20%-40%.
Furthermore, steel shot can be used as a pretreatment before coating, forming a uniform surface roughness, enhancing coating adhesion and durability, thereby reducing production costs. With the rise of new energy vehicles, the demand for high-performance steel shot is increasing daily—more than 38% of global steel shot demand comes from the automotive and aerospace industries.
